VISOKO, Bosnia-Herzegovina -- Researchers on Wednesday unearthed geometrically cut stone slabs that they said could form part of the sloping surface of what they believe is an ancient pyramid lying beneath a huge hill.

Archaeologists and other experts began digging at this central Bosnian town last week to explore the team leader's theory that the 2,120-foot hill covers a step pyramid, which would be the first ever found in Europe.

"These are the first uncovered walls of the pyramid," Semir Osmanagic, a Bosnian archaeologist who studied the pyramids of Latin America for 15 years, said of the stonework found Wednesday.

"We can see the surface is perfectly flat. This is the crucial material proof that we are talking pyramids," he said.

Osmanagic believes the structure will prove to be 722 feet high, or a third taller than Egypt's Great Pyramid of Giza.

The huge stone blocks discovered Wednesday appeared to be cut in cubes and polished.

"It is so obvious that the top of the blocks, the surface is man-made," Osmanagic said.

Earlier research on the hill, known as Visocica, found that it has 45-degree slopes pointing toward the cardinal points and a flat top. Under layers of dirt, workers discovered a paved entrance plateau, entrances to tunnels and large stone blocks.

I'll admit I was skeptical from reading the description DT pasted. Too many difficult questions that weren't even attempted at answering, not the least of which being "Why was this never found before?"

Normally, when confronted with something this fantastic (incredible? unbelievable? Funny how all of the words that mean "obviously fake" have been co-opted by superhero comics), I would seek alternate sources for the data, and do more research. However, since the "discovery" would not have affected me either way, and I'm not really an archaeology buff, my giveashit meter was far too close to the E for me to bother.
